Zusatztipps für die Zubereitung

Using a 10-inch oven-safe skillet is essential for transitioning from the stovetop to the oven safely and ensuring even cooking. Always let the frittata rest for 5 minutes after baking; this allows the structure to firm up, making it much easier to slice into clean wedges.

Varianten und Anpassungen

This recipe is highly customizable based on what is in your kitchen. You can swap the primary vegetables for spinach, mushrooms, or asparagus. For a dairy-free alternative, use plant-based milk and omit the cheese or use your favorite vegan cheese substitute.
